Kilogram-force is a traditional, non-SI unit of force equal to the force exerted by gravity on a 1-kilogram mass at standard gravitational acceleration.
Kilogram-force was widely used in engineering practice before the SI system standardized on the newton; it still appears in legacy documents, torque wrenches and some pressure gauges.
Measurement system: Gravity-based unit (non-SI). SI equivalent: 1 kgf = 9.80665 N.
